doh, of course when I come to look more closely at the merge, I realise that
in fact the cats and ebsa both use options EBSA285, so I can change the code
to #ifdef cats, and completely eliminate the defopt EBSA285 and opt_ebsa285.
Perhaps I should really have used ebsa as the arch dir name instead of cats.
